TL;DR: How alterations in glutathione status, such as those observed during stress, may participate in signal transduction cascades are discussed and how these alterations are integrated to fine-tune photorespiratory and respiratory metabolism and to modulate phytohormone signalling pathways.

TL;DR: This work has suggested that carbohydrate accumulation in leaves when there is an imbalance between source and sink at the whole plant level can lead to decreased expression of photosynthetic genes and accelerated leaf senescence, and in a high CO2 world this may become a more prevalent feature of photosynthesis regulation.

TL;DR: Photosynthesis is a well-established source of reactive oxygen species (ROS) in plants and an efficient antioxidant network is also essential to minimize ROS production.

TL;DR: Control of glutathione concentration and redox state is due to a complex interplay between biosynthesis, utilization, degradation, oxidation/reduction, and transport, and all these factors must be considered in order to evaluate the significance of glutATHione as a signalling component during development, abiotic stress, or pathogen attack.

TL;DR: The contributors highlight many areas of current research and explore the causes of photo-oxidative stress in plants and the environmental consequences, as well as the biochemistry, genetics, and molecular biology of protective systems.
